MOUNTING MEANS FOR LOCKS.

Application filed February 13, 19225. Serial No. 8,963.

To all whom t may concern:

Be it known that I, CHARLES LEDIN, a citizen of the United States, and resident- .of Stamford, in the -county of Fairfield and i; State of Connecticut,have invented certain new and useful Improvementsin Mountingv Means for Locks; and I do hereby declare the following to Abe aV full, clear, and exact description of the inventiomrsuch as will enable others skilled in the art to which it a-ppertains to make yand use the same.

This invention relates to improvements in i'nounting means for locks land more particularly to adjustable devices for mounting a cylinder lock for use with a rim lock, in doors,-one object of the invention being 'to provide simple and etlicient means which shall be adaptable to doors ydiffering in thickness, for carrying a cylinder lock intended for use wit-h a rim lock, and to so construct and arrange adjustably connected devices for a cylinder lock in a jbore in a door, mounting devices that said ydevices cannot be rotated or moved longitudinally after having been installed.

lith this and other objects in view, the invention consists in certain novel features of construction and combinations of parts as hereinafter set forth and pointed out in the claims.

ln the accompanying` drawings;

Figure 1 is a sectional 'view showing an embodiment of the invention when applied to a door of one thickness;

Figure 2 is a similar view showing the improvement applied to a door having less thickness Figure 3 is an outside end view;

Figure 4 is an inside end view with the cover plate of t-he rim lock casing removed;

Figures 5 and 6 are detail perspective views of the tubes or shell 5 and 6, and

Figure 7 is a side view.

A portion of a door is represented at 1 and is provided with a bore or opening 2 for the accommodation of the mounting devices in which a cylinder lock 3 is located. My improvements are intended for use with a rim lock and while it need not be herein shown and described, I have indicated at 4 the cover plate of a rim lock casing, with which plate, a part of the mounting device for the cylinder lock cooperates.

My improved mounting devices comprise three tubes or sleeves 5, 6 and 7. The base tubeis inserted into the bore or opening 2 1n the bore, and lmay be somewhat shorter than the length of the latter in the case of ay thick door. The tube or shell 5 with dialnetrically opposite series of slots or holes 8, 9,- the slots or openings of each series `being suitably spaced apart longitudinally of the tube or shell. The tube or sleeve 6 (which may be .conveniently made of sheet metal), is provided at one end with forwardly projecting lugs 10, 11, the lugs 10 being disposed Adiametrically opposite each :other and said lugs are adapted to project through suitable slots or openings in the cover plate 4 of the rim lock casing and riveted over or not as desired. The tube or shell 6 is also provided with outwardly projecting lugs or wings 12 (which may be cut from the metal of the tube or shell and bent outwardly) 4and these lugs or wings will, when the tube or shell 6 is passed over the tube or shell 5, rest against the inner face of the door, as illustrated in Figures 1 and 2. The tube or shell 6 is also provided with fingers or catches 13 (which maybe cut'lfrom the metal of said tube or shell) provided with inwardly projecting portions 14 to enter holes S or 9 in the base tube or shell 5.

The cylinder lock 3 is suitably secured within the base tube or shell 5, and this may be accomplished. by forcing parts of the metal of said tube o-r shell 5 into pits or depressions 16 as illustrated in Figure 4.

In applying the device to a door, the tube or shell 6 will he slipped onto the tube or shell 5 and the two catches 13 bent down so that their inwardly projecting portions 14 will enter the holes or openings 8 or 9 according to the thickness of the door. This will allow the out-turned wings or lugs 12 to bear against the inner face of the door and the lugs or spurs 10-11 to enter the receiving slots in the cover plate 4 of the rim lock. When thus installed the tubes or shells 5 and 6 as well as the cylinder lock will be prevented from turning or longitudinal movement. The. cylinder ring or tubu lar shell 7 will be passed into the bore in the door and made to surround a portion of the base shell or tube 5 as shown in Figures 1 and 2 and the flange 7iL of said ring or shell 7 will engage the outer face of the door, to which it may be secured by fastening de vices such as small nails 15.

In Figure 1 the devices are shown as applied to a thick door and the catches 13 of tube or shell 6 engaging in the slots or openings 8 oi' the base shell or tube 6, while in Figure 2, the application of my improvements to a thinner door and the catches 13 of tube or shell 6 engaging in the slots or opening 9 in the base shell 5. In theV drawing, two slots or openings 8 and 9 are shown at opposite sides of the base tube or shell 6, but if desired, a greater number may be employed to permit relative further adjustment of these tubes or shells.

I-Iaving fully described my invention, what I claim as new and desire to secure by Letters-Patent, is

l. Mounting devices for cylinder locks, comprising relatively adjustable tubes or shells to enter a bore in a door, one of said tubes or shells having projecting portions to pass through holes in a member of a rimlock casing, said tube or shell also having a laterally projecting member to engage a 'face of the door.

2. Mounting devices for a cylinder lock, comprising telescopic members relatively adjustable longitudinally and adapted to occupy a bore in a door, one of said members having forward and also lateral projections at one end adapted to be disposed adjacent to and beyond a face of the door.

3. Mounting means for a cylinder lock, comprising telescopic members, one of said members having catches to adjustably engage the other member, said first-mentioned member also having forward and lateral projections at its inner end portion adapted to be disposed adjacent to and beyond a face of the door.

4. Mounting devices for a cylinder lock, comprising telescopic tubes, one of said tubes having diametrically opposite series of holes andtheother tube provided with catches to engage in any hole of each series inthe firstmentioned tube, and inward and lateral projections at the inner end portion of one of said tubes.

5. Mounting devices for a cylinder lock, comprising two relatively adjustable tubes, one of said tubes having engaging means for the .inner facel o1 a door and also having engaging means for a member of a rim lock casing, and a third tube embracing one of said first-mentioned tubes and having a flange to be secured to the outer race of a door.

The combination with a member of a rim lock casing, of two telescopic tubes, means for securing said tubes together at dii'erent longitudinal adjustments, one of said tubes having projections to engage a part of a rim loclr casing and having other projections to engage the inner face of a door, a cylinder lock secured in one of said tubes, and a third tube embracing one of said first-mentioned tubes and adapted to be secured at the outer face of a door.

In testimony whereof, I have signed this specification.
